Pros are using variations of it on heavily oiled PBA conditions all the time.
Say it gives them midlane. However it is really solving a head, and mid oil problem in getting the ball to rev earlier.
Very often variations used on fresh oil like patterns A and C.
However, the ball is set up to rev early but not charge at the transition to the dry! That's the secret of that variation.
